The interaction between molecular electronic transitions and electromagnetic fields can be
enlarged to the point where distinct hybrid light–matter states, polaritons, emerge. The …

Coumarins are a very large family of compounds containing the unique 2 H-chromen-2-one
motif, as it is known according to IUPAC nomenclature. Coumarin derivatives are widely …

Ultrastrong coupling between light and matter has, in the past decade, transitioned from a
theoretical idea to an experimental reality. It is a new regime of quantum light–matter …

It is possible to modify the chemical and physical properties of molecules, not only through
chemical modifications but also by coupling molecules strongly to light. More intriguingly …

Angle-independent narrowband emission is required for many optoelectronic devices,
ranging from high-definition displays to sensors. However, emerging materials for …

The interaction of light and matter at the single-photon level is of central importance in
various fields of physics, including, eg, condensed matter physics, astronomy, quantum …

There have recently been remarkable achievements in turning light–matter interaction into
strong-coupling quantum regime. In particular, room-temperature plexcitonic strong coupling …

Exciton polaritons, arising from the interaction of electronic transitions with confined
electromagnetic fields, have emerged as a powerful tool to manipulate the properties of …

The Dicke model, which describes the dipolar coupling between N two-level atoms and a
quantized electromagnetic field, seemingly violates gauge invariance in the presence of …

We explore the electroluminescence efficiency for a quantum mechanical model of a large
number of molecular emitters embedded in an optical microcavity. We characterize the …
